I had the same problem a few days ago. Today I finally got it. The main thing I noticed is the lights on mine never did flash in the sequence the manual describes. I finally tossed the book down, reset the homelink and followed the instructions to a point.(ignored light instructions) Mine went to a fast red flash (not slow) then followed the instructions again for putting the remote close to the mirror. I then hopped out got on a ladder & hit the garage door opener program button(usually red). Then hopped back in the truck real quick and hit the same button a few times like it says. Hope you get it working.
